OKC brings us another piece of American history with the Air Force Survival Knife (AFSK). The AFSK is used by several branches of the U.S. Armed Forces and is made right here in the USA. It features a 1095 carbon steel full tang blade with a zinc phosphate finish and sawteeth on the spine. The natural leather handle will provide a great grip in all conditions and looks great with the classic leather sheath. As much a functional field knife as it is a collectible, the AFSK is super tough and easy to sharpen in the field thanks to its slightly lower Rockwell hardness and the included sharpening stone.
